In twenty years of reform-and-open up policy, China realized about 10% annual rate of growth and entered into the interdependent relations in the world, as a Regional Power.Our research analyzed these changes in China, focusing on seven specific themes which included center-local relations, marketization of economy, state-society relations, human beings in development, historical continuity and discontinuity, relations with the ethnic-minorities and Taiwan, Hongkong, China in Asia-Pacific region. The general team engaged in the work for contriving the new method of analysis, for organising interdisciplinary research on the structural changes, and in promoting the international exchanges and in the public information. We held six times general research assembly, invited 30 foreign scholars, collaborated with the research team on Slavic World, held symposium with Shanghai Academy of Social Sciences twice, published 12 volumes of Chinα Area Studies Series and collected basic materials.We talked over and over again on above mentioned seven themes and came to the provisional conclusion ; 1) if we assume that there are three stages of metamorphosis of China, the first structural change, the second structural change and systemic change which goes with the marketization and democratization, 20 years of reform and open-up policy was the beginning of the first stage. Now China is passing into the second stage urged by the Asian monetary crisis. 2) The feature of the first stage is that the traditional structure of dualism (center/local, planned/market, state/society) has changed into trilateral structure (center/middle/lowest, planed/half market/market). 3) When we see into the future of China, we can use the experience of Taiwan and South Korea, as the useful vandage, which transfered from the low development to economic growth, from the authoritarian-regime to the democracy (East Asian Model).
